ABSTRACT:
A cyclical machine forming tool utilizes positionally justified form knives so that, nominally, a selected 80 out of 120 total stripped wire ends of flat ribbon cable may be selectively simultaneously formed, for bent, into a contour such as is useful for soldered attachement to printed circuit cards. Positional justification of wire-forming hammer elements called form knives, nominally 41 in number, across a variable distance, nominally 1.676.+-.0.009 inches, is expediently repetitively accurately accomplished by wedging them apart with interspersed counterposed knife elements, nominally 40 in number, called adjuster knives. Two such tools may be deployed back to back in staged sequence with other ribbon cable positioning, clamping, severing, and end stripping elements so that a multi-conductor flat ribbon cable may be severed at a desired length, have conductors stripped of insulation on both severed ends, and have stripped conductor wires of both ends selectively formed in an efficient semi-automated process.
